[RESOLVED]: Nortel IP1535 not registering with Asterisk

I cannot seem to get the Nortel IP1535 to hit the registration server. It takes the username, password, proxy address and says ‘registering… failed.’ I am wondering if there is a setting I am missing within the phone but I cannot seem to find any documentation on it. Any advice on this issue would be greatly appreciated.

Everything is up and running now! It’s always great fun when you make a typo in the dialplan.
